You mentioned that you dump directly to "a" tape dataset... isn't that putting
an awful lot of faith and hope into one measely tape? I would, if I were doing
that, be using 2 tapes written concurrently (just in case one of my tapes
broke or otherwise failed). Call it "RAIT 0" (a la RAID 0) if you like.
I would also be considering making the output tape blksize closer to 256K as
you mentioned.
RAIT 0 would be something like writing half of the records to one tape
and the other half to another one in parallel. If I understand your
suggestion correctly, what you suggest is concurrent backup on two tape
drives. That should aptly be called "RAIT 1".
